To determine if there was a loss or gain from Bija's motorcycle transactions, we need to look at the total cost and the total selling price. 
 
 Bija bought two motorcycles, each for ₹37,842. 
 The total cost of the motorcycles is: 
 ₹37 , 842 × 2 = ₹75 , 684 
 He sold one for ₹39,246 and the other for ₹36,842. 
 The total selling price is: 
 ₹39 , 246 + ₹36 , 842 = ₹76 , 088 
 Now, we find the difference between the total selling price and the total cost: 
 ₹76 , 088 − ₹75 , 684 = ₹404 
 Bija gained ₹404 from these transactions. 
 
 The distance between the city in India and the city in the United States is 24,800 km. The speed of the aeroplane is 800 km/h. To find out how many hours the plane is in the air, we divide the total distance by the speed: 
 
 Time = 800 km/h 24 , 800 km ​ = 31 hours 
 The aeroplane uses 400 litres of fuel per hour. 
 So, the total amount of fuel used for the journey is: 
 400 litres/hour × 31 hours = 12 , 400 litres 
 The journey requires 12,400 litres of aviation fuel. 
 
 Each participant in the relay race runs 750 m, and there are 62 participants. To find the total distance run by all participants, multiply the distance each participant runs by the number of participants: 
 
 750 m × 62 = 46 , 500 m 
 Convert meters to kilometers by dividing by 1,000: 
 1 , 000 46 , 500 m ​ = 46.5 km 
 The total distance travelled by them is 46.5 kilometers.
